Only for finding the bootloader itself (the embedded core.img), not for

It is; the difference is that Grub2 embeds much more data, typically ~25
KiB, and thus it is not safe to embed it into a partition that contains
a filesystem.

The Right Way™ to overcome these difficulties is to embed Grub into a
partition that does not contain any data. With GPT you even have a
standard for that, the BIOS Boot partition.
